World leaders must agree a deal to tackle global warming within the next year or risk losing our way of life as we know it, Ed Davey, the energy secretary has warned ahead of major international negotiations in Lima.

'By 2018, no new cars, homes, schools, factories, or electrical power plants should be built anywhere in the world, ever again, unless they’re either replacements for old ones or carbon neutral. Otherwise greenhouse gas emissions will push global warming past 2˚C of temperature rise worldwide, threatening the survival of many people currently living on the planet.'
